I bought this product with 16 mm inner diameter to use for a shaft with a diameter of 16 mm but it was 15.9 mm when measuring the inner diameter with a digital calipers without entering the shaft. There was a notation of width tolerance ± 0.1, but there was not such a notation of inner dimension. Since it can not be helped, it was used with the inside diameter enlarged with a file. It would be nice to have accurate dimensional accuracy.
